摘要： Devices, systems, and methods for modifying an existing electrical circuit to enable a conventional mechanical switch to integrate with and operate smart devices, while also providing continuous power supply and cooperating with external operation of the smart devices (e.g., via a mobile device application, smart controller, etc.). The smart device thus is operable both via the physical switch and via a home automation system, without loss of power to the smart device computer and transmitter components caused by use of the wall switch. This may be done via a replacement switch or faceplate which effectively bypasses the physical switch to ensure continuous power to the smart device while also inferring and transmitting the toggle state of the switch by measuring an amount of current through the faceplate.
